EA OLED SERIES With its EA OLED series ELECTRONIC ASSEMBLY launches worldwide the first display family with OLED-technology for direct mounting and soldering. In comparison to standard displays there’s no FFC/FPC cable/connector that may loose contact, this OLED series will be soldered directly or put into a standard 2.54 mm precision socket. It is designed for compact handheld equipment and provides a lot real advantages:

- Extreme compact (68x51mm) with a large viewing area (64x37mm) - Super flat with 2.4 mm (without frontal protection glass) - SPI and I²C interface - Simple mounting with direct soldering - Ex stock available from 1 pc. off - Long life time (80,000 h for yellow) - Extreme wide temperature range (-40..+80°C) - Fast response time (10µs), no afterglow

VERSIONS The EA OLEDL128-6 is available in 3 different versions: EA OLEDL128-6GGA / Allround This module is perfect for rough environment. An additional frontal glass protects the display against scratch, shock and UV light. Thanks to its integrated polariser there’s no need for an additionally smoked glass. EA OLEDL128-6LGA / Flat This module is the standard module and does fit for the most applications. The flat design (2.4 mm) makes the display perfect for smallest equipment. The background is always deep black for best contrast. EA OLEDL128-6NGA / Design solution This version is to become favourite for assembly behind a smoked glass. There’s no protection glass or polariser which makes it with 2.4mm very flat. The advantage is a doubled brightness which makes it perfect in combination with the smoked glass. We recommend to put it behind a fully smoked glass front to make only the graphic visible, no edges, no print, no overhang and hygienic to clean.

COLORS (CUSTOM MADE) The standard colors are yellow and white. The flat version EA OLEDL128-6LGA is on customers request available in 3 more colors. The minimum order quantity is 10,000 pcs., lead time is about 20 weeks. Samples are available on request. Interface and software are 100% compatible. The yellow color provides highest brightness and longest life time.

DATA TRANSFER 4-WIRE SPI (8 BIT) Data transmission for SPI is unidirectional, that means that data can only be written, there’s no data read option. Selection for writing data or command is done with the D/C line. A busy check is not necessary at all. Clock rate may be up to 10 MHz. Data transmission is based on SPI mode 3, MSB first. For more details please refer to the controllers data sheet SSD1309.

DATA TRANSFER 4-WIRE SPI (9 BIT) Data transmission for SPI is unidirectional, that means that data can only be written, there’s no data read option. Selection for writing data or command is done with the first bit of the 9 bit data transfer. A busy check is not necessary at all. Clock rate may be up to 10 MHz. Data transmission is based on SPI mode 3, MSB first (9 bit). For more details please refer to the controllers data sheet SSD1309.

DATA TRANSFER I²C The I²C mode provides a bi-directional data transmission: That means that data can be written and read. With the pin SA0 the I²C address can be changed, so up to 2 displays may be driven on 1 bus. The clock rate may be up to 400 KHz. Please make sure when defining the pull-up resistors that the internal resistance of the display is 600..1000 . This affects the low level when reading data and ACK bit. Attention: When reading data, after the command for page- or column address there need to be a dummy read (discard the first byte).

Control byte: Co (Continuation bit) = 0 Display data do follow; 1 refer D/C bit t

ACCESSORY: SOCKET EA FL-20P Using a 20-pin socket makes the display replaceable and adapts the height. Those socket may also be soldered automatically by wave soldering or reflow process. Each display requires 2 pcs.

ACCESSORY: TOUCHPANEL EA TOUCH128-2

As an accessory there is an analogue touchpanel available. It comes with a self-adhesive glue on its rear side. Connection is done via FFC, pitch 1.0 mm. Any standard ZIFF connector can be used (e.g. EA WF100-04S). Bending radius is minimum 5 mm. Interfacing to a processor can be either done by an external touch panel controller or with a controller that is featured with analogue input. The touch panel is similar to a potentiometer: connecting a voltage of e.g. 3.3 V to the pins Top-Bottom makes it possible to read out a voltage on pin Left or Right which is linear to the Y-coordinate of the pressed point. The X-coordinate will result when the voltage will be supplied to Left-Right and measurement is done at Top or Bottom. The pinout of the connecting cable is shown in the drawing. Only in combination with the EA OLEDL128-6GGA.

ACCESSORY: ZIFF CONNECTOR EA WF100-04S

The ZIFF connector matches perfect to the touch panel EA TOUCH128-2. It provides 4 pins with 1.0 mm pitch. Connection is bottom contact. Top contact version is called EA WF100-04T.

Note: - OLED displays are generally not suited for wave or reflow soldering. Temperatures of over 80°C can cause lasting damage. - The surfaces of the displays are protected from scratching by self-adhesive protective foil. Please remove before mounting - OLED are generally designed for indoor application. When be used outside they need to be protected against sunlight (UV radiation) and humidity, water and dust.
